    need a better picture, or markings on top of components.

    Variable Power Supply 0-24vdc 5A more...

    this schem. works great, i got samples from maxim few years ago, and it's been working non-stop since :) might be noisy in audio apps. if output caps aren't low ESR.

    frequency to voltage noise filtering

    well... i thik that the real broblem isn't noise, but too long pulse period... seeing schematics would help.

    Muscular Bio-Stimulator

    I think that you have too high VA rating in your transformer... I used 230 -> 9 Vac 0.8VA transformer in my version. And be sure that your transformer is connected right. ie. secondary connected between emitter of Q2 and ground.

    Dual LM3886 Bridged Amp.

    How about both? Bridged and single ended, wich one you want to by mono switch.

    Dual LM3886 Bridged Amp.

    Has anyone bumped into amplifier that is built from 2 LM 3886 Power amp IC's and can be Bridged? I'm making schematics and PCB (again) because old version got lost... actually i'm gonna make even that double (4ch. amp. 2ch. Bridged) :P Is there need for such amp for anyone? i'll put project...

    Who is using the oldest computer?

    I still use good old C-64 for gaming... (i hate those buggy emulators) and i still have few original games that can't be found from internet ;D

    TV: High Definition, Progressive Scan

    3: yes, they are liars, older tv's mostly don't show clearer picture because the filters just aren't designed considering higher horizontal/vertical frequencies as in hdtv/progressive scan is intended to. it can be worse though.

    attenuator cord for taping off a scanner

    a simple attenuator uses just 2 resistors, so that impedance would stay in acceptable level u should know both output and input impedances of both devices. then it's quite easy to calculate values and make attenuator from pot and 1 fixed resistor, or just 2 fixed resistors.

    EAGLE Layout Editor question (simple)

    that's why i stopped using eagle... >:(

    Free sample chips!

    Analog Devices: i've just build a 2x120W amplifier ONLY by using FREE SAMPLES!!! ;D
